Warning!
The safety regulations for operation in 3.2. must be adhered
necessarily!
The heaters are adjusted in the factory and can be used unlimited wit-
hout a change of the CO adjustment up to an altitude of 1500 m above
2
MSL and up to 2000 m above MSL if that is a short stay in such condi-
tions (pass crossing, break).
In case of a permanent heater operation above 1500 m the CO
must be readjusted, due to a negative change of the exhaust gas values
in result of the decreased air density.
It is also recommended to adjust the CO
technical data if combustion air supply or exhaust gas applications are
used.
After heater installation, bleed the water system and the fuel supply sys-
tem carefully. In this process it is mandatory to fill the suction line and
the fuel filter of the heater completely. Spheros recommends the usage
of a separate bleeding unit. Follow the appropriate instructions provided
by the vehicle manufacturer. Verify the fuel supplied to the heater is
bubble-free.

ATTENTION:
Do not use the fuel pump to fill / bleed the fuel system!
Generally, the hook-up of the heater to the vehicle power grid must be
done only after filling / bleeding the fuel system in order to prevent a
premature start of the fan motor/fuel pump.
Conduct a test run of the heater to check all the water and fuel connec-
tions for leaks and to ensure that they are secure. If the heater suffers a
fault during operation, the fault must be located and remedied according
to given in the workshop manual instructions.
ATTENTION:
In the event no fuel comes to the fuel pump during initial start-up
(dry running), there is a risk that the fuel pump will be damaged!
In order to achieve a maximum service life, combustion times of less
than 120 seconds are to be avoided.
13.2. Control head AC/DC
When commissioning the AC / DC control head for the first time, it must
be ensured that the circulating pump is switched on during heating and
remains on at least 120s after heating.
